Peanut allergy mystery: why do some kids outgrow it?

NCT ID NCT02497261

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study follows 200 children who have tested positive for peanut allergy but avoid eating peanuts. Researchers will use a gold-standard food challenge to see which children are truly allergic and which have outgrown their allergy by age 5. The goal is to understand if avoiding peanuts makes allergies more likely to persist. No treatment is given, and the challenge does not change a child's ability to tolerate peanuts.
